XAML Values

oneOrMorePathFigures
One or more PathFigure object elements. Object elements defined here become members of the PathFigureCollection collection when code accesses the Figures property at run time.

The PathGeometry type exposes the following members.

Constructors

	Name	Description
	PathGeometry	Initializes a new instance of the PathGeometry class.

Properties

	Name	Description
	Bounds	Gets a Rect that specifies the axis-aligned bounding box of the Geometry. (Inherited from Geometry.)
	Dispatcher	Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)
	Figures	Gets or sets the collection of PathFigure objects that describe the contents of a path.
	FillRule	Gets or sets a value that determines how the intersecting areas contained in the PathGeometry are combined.
	Transform	Gets or sets the Transform object applied to a Geometry. (Inherited from Geometry.)

Methods

	Name	Description
	CheckAccess	Determines whether the calling thread has access to this object. (Inherited from DependencyObject.)
	ClearValue	Clears the local value of a dependency property. (Inherited from DependencyObject.)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetAnimationBaseValue	Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	GetValue	Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ReadLocalValue	Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)
	SetValue	Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.)
	ToString	Returns a string representation of this PathGeometry. (Overrides Object.ToString().)

Fields

	Name	Description
	FiguresProperty	Identifies the Figures dependency property.
	FillRuleProperty	Identifies the FillRule dependency property.

Remarks

Each PathGeometry object defines a collection of PathFigure objects. Each of the PathFigure objects is composed of one or more PathSegment objects, such as ArcSegment and LineSegment, which actually define their shape.

The filled area of the PathGeometry is defined by taking all of the contained PathFigure objects that have their IsFilled property set to true and applying the FillRule to determine the enclosed area.
